You weren't the most.. popular.. person in school.
You had no friends, and literally nobody even tried to approach you. You were seen as weird, strange, and ugly; you didn't fit the beauty standard.
The kind of student a teacher would place the misbehaving one beside, simply because they knew they wouldn't continue interrupting the lesson if they were beside you.
For example, Kyle Gilmore just got sat beside you for throwing a paper ball at his friends head. He stares down at you for a moment, before plopping his bag on the desk and slumping in the chair beside you.
He was the opposite to you. Being in a rock band with his friends, he was quite popular, and always loud and misbehaving. He thought you were a freak, and you could tell by the side-glances he was giving you already.
